7.3. FPGA-to-HPS Bridge

The FPGA-to-HPS bridge provides access to the peripherals in the HPS from the FPGA. This access is available to any master implemented in the FPGA fabric. You can configure the bridge slave, which is exposed to the FPGA fabric, to support the ACE-Lite protocol, with a data width of 128 bits.

Table 81.   FPGA-to-HPS Bridge PropertiesThe following table lists the properties of the FPGA-to-HPS bridge, including the configurable slave interface exposed to the FPGA fabric.
